2017-04-08ver_linux: Use /usr/bin/awk instead of /bin/awkSaul Wold
Most Linux distributions contain awk in /usr/bin by default, not in /bin. This script's suggested use is for creating version information for bug reporting. This has been tested on a number of different distributions, including Fedora, Ubuntu, OpenSUSE, Debian, Centos, Arch Linuxi, and Poky!

2017-03-30x86/build: Mostly disable '-maccumulate-outgoing-args'Josh Poimboeuf
The GCC '-maccumulate-outgoing-args' flag is enabled for most configs, mostly because of issues which are no longer relevant. For most configs, and with most recent versions of GCC, it's no longer needed. Clarify which cases need it, and only enable it for those cases. Also produce a compile-time error for the ftrace graph + mcount + '-Os' case, which will otherwise cause runtime failures. The main benefit of '-maccumulate-outgoing-args' is that it prevents an ugly prologue for functions which have aligned stacks. But removing the option also has some benefits: more readable argument saves, smaller text size, and (presumably) slightly improved performance. Here are the object size savings for 32-bit and 64-bit defconfig kernels: text data bss dec hex filename 10006710 3543328 1773568 15323606 e9d1d6 vmlinux.x86-32.before 9706358 3547424 1773568 15027350 e54c96 vmlinux.x86-32.after text data bss dec hex filename 10652105 4537576 843776 16033457 f4a6b1 vmlinux.x86-64.before 10639629 4537576 843776 16020981 f475f5 vmlinux.x86-64.after That comes out to a 3% text size improvement on x86-32 and a 0.1% text size improvement on x86-64.

Adding a hook into free_reserve_area() that informs ftrace that boot up init text is being free, lets ftrace safely remove those init functions from its records, which keeps ftrace from trying to modify text that no longer exists. Note, this still does not allow for tracing .init text of modules, as modules require different work for freeing its init code.

2017-03-11scripts: objdiff: Ignore debug info when comparingStephen Boyd
If the kernel is configured to be built with debug symbols, or has bug tables, comparing files may not work if line numbers change. This makes comparing object files with these options harder to do. Let's strip out the debug info and drop the __bug_table here so that we don't see false positives. There may be other things to drop later, and it may be architecture specific, but this works for me with my ARM64 build.

A check was added to make sure that all jump label entries were 4 bytes aligned, but powerpc didn't work that way for modules. Adding an alignment in the module linker script appeared to be the best solution. - Jump labels also added an anonymous union to access those LSB bits as a normal long. But because this structure had static initialization, it broke older compilers that could not statically initialize anonymous unions without brackets. - The command line parameter for setting function graph filter broke the "EMPTY_HASH" descriptor by modifying it instead of creating a new hash to hold the entries. - The command line parameter ftrace_graph_max_depth was added to allow its setting at boot time. It uses existing code and only the command line hook was added. This is not really a fix, but as it uses existing code without affecting anything else, I added it to this release.

2017-03-03module: set __jump_table alignment to 8David Daney
For powerpc the __jump_table section in modules is not aligned, this causes a WARN_ON() splat when loading a module containing a __jump_table. Strict alignment became necessary with commit 3821fd35b58d ("jump_label: Reduce the size of struct static_key"), currently in linux-next, which uses the two least significant bits of pointers to __jump_table elements. Fix by forcing __jump_table to 8, which is the same alignment used for this section in the kernel proper.

The '__unreachable' and '__func_stack_frame_non_standard' sections are only used at compile time. They're discarded for vmlinux but they should also be discarded for modules. Since this is a recurring pattern, prefix the section names with ".discard.". It's a nice convention and vmlinux.lds.h already discards such sections.

2017-02-28drm: Introduce drm_connector_{get,put}()Thierry Reding
For consistency with other reference counting APIs in the kernel, add drm_connector_get() and drm_connector_put() functions to reference count connectors. Compatibility aliases are added to keep existing code working. To help speed up the transition, all the instances of the old functions in the DRM core are already replaced in this commit.

2017-02-27checkpatch: warn when formats use %Z and suggest %zAlexey Dobriyan
vsnprintf extension %Z<foo> is non-standard C. Suggest the use of %z instead. Miscellanea: - Correct the misuse of type string PRINTF_0xDECIMAL type strings are supposed to be uppercase only. Fix this and add tr/[a-z]/[A-Z] to the type check in case I forget this again sometime in the future. - Improve the mechanism to find these defects so all 3 current checks are done on the format string [joe@perches.com: correct the misuse of type string PRINTF_0xDECIMAL, improve the mechanism to find these defects] Link: http://lkml.kernel.org/r/4e3ad74b0c9dc229b06018a2d79655308ddbbebd.1484014173.git.joe@perches.com Link: http://lkml.kernel.org/r/20170109235955.GA6787@avx2 Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
